Greatest Common Divisior

We found the divisors of 55, 15, 83, 53 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 55, 15, 83, 53 is 1.

Therefore, GCD of numbers 55, 15, 83, 53 is 1

Given Input Data is 55, 15, 83, 53

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 55 is 5 x 11

Prime Factorization of 15 is 3 x 5

Prime Factorization of 83 is 83

Prime Factorization of 53 is 53

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(55, 15) = 165

GCD(55, 15) = ( 55 x 15 ) / 165

GCD(55, 15) = 825 / 165

GCD(55, 15) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 83

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(5, 83) = 415

GCD(5, 83) = ( 5 x 83 ) / 415

GCD(5, 83) = 415 / 415

GCD(5, 83) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 53

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 53) = 53

GCD(1, 53) = ( 1 x 53 ) / 53

GCD(1, 53) = 53 / 53

GCD(1, 53) = 1

GCD of 55, 15, 83, 53 is 1
